OVERVIEW
Sharpe
®
electric quarter-turn actuators offer a wide range of torque output models. The product
design is based on a self-locking worm drive principal, which provides for a smooth running,
dependable, robust drive system. All models are ISO 5211 compliant and most have a visual
position indicator on top of actuator cover and manual override
LUBRICATION
The gearbox of the Sharpe actuator is enclosed, and it has already been lubricated sufficiently
with high temperature lubricant at the factory sufficient for use for up to two years.
IMPORTANT NOTICES & MAINTENANCE
Notices:
Make sure the voltage is correct before wiring.
Turn off power before for maintenance purposes.
Seal the casing and conduit entrance after wiring to prevent dust or water contamination.
The angle of installation must between 0~180°. Do not install upside down or below the
horizontal.
Do not install when hazardous or explosive gases may be present.
The frequency of open and close is restricted based on duty cycle. Avoid too high
frequency.
When more than one electric actuator needs to operate simultaneously, please connect
individually.
Always connect the ground wire to the inside of the electric actuator.
Not intended for vacuum spaces and avoid installing near explosive atmospheres.
To avoid functional failure caused by statics, do not touch any components on the PCB
with metal tools or bare hands.
Storage:
The actuator should be placed in a clean and dry place, and protected from the weather
and extreme vibration.
If actuator needs be stored outside, it must be protected from excess moisture, dust,
and weather.
